Emma Watson may have denied that she's up for playing any rauchy roles in Fifty Shades Of Grey, but the actress has now taken to Twitter to strip down for another cause, to raise environmental awareness.

The Harry Potter star tweeted her support for James Houstons's book of celebrities posing nude to raise awareness for the environment, with the book's proceeds going to Global Green USA, a nonprofit organisation focused on sustainability.

"My friend is supporting GlobalGreenUSA with his book Natural Beauty. It's out now. : ) X," she wrote on Twitter, posting a bare-shouldered portrait of herself.

The actress recently slammed any rumours that she would be involved in the sexual Fifty Shades movie, despite being quite happy to pose in the nude for other causes.

Whilst Universal Pictures and partner Focus Features had both previously denied the casting rumours, Emma has obviously caught onto the latest reports and earlier this week took to twitter in an attempt to play down the speculation, writing: "Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life."

Author EL James has also had her say, tweeting after the headlines last week that "No casting decisions have been made yet."

Rumours of Emma's involvement in Fifty Shades have been circulating since the project was announced last year with the actress previously speaking out on the speculation last summer, admitting that even her friends were convinced she was going to play Ana: “I told them just because there are 60 articles on the Internet doesn’t mean it’s any less true than if there are three or four,” Watson said back in July.

“The thing is I’m not going to go out there every time someone attaches me to a film to say no or release a statement.”

Who do you think should play Miss Steele?
